JOURNAL-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 375,291, dated December20, 188'].

Application filed June 29,1887. Serial-No. 242,895. (No model.)

' which the following is a specification.

This invention relates to means for auto matically lubricating thejournals and bearings of machinery, and has for its object theproduction'of a lubricator which will be simple, cheap, efficient, andreliable; which will lubricate two or more journals from a singlereservoir; which will supply the lubricant in desired quantities; whichwill supply the lubricant from a reservoir to a supplemental orintermediate receiver proportionately as the lubricant is used from suchreceiver for maintaining the lubricant at a predetermined or fixed leveltherein, so that the dippers or diparms willalways receive an equalamount of lubricant and deposit an equal amount in the conveying ductsor tubes which lead to the journals or bearings; which will beadjustable to regulate the feed of lubricant; which will have anautomatic friction-brake, thereby reducing the number of parts bydispensing with a detent-pawl, and which will have-means for throwingthe lubricator out of gear and holding it out of gear when desired.

In the drawings, Figure 1 is a side view of a lubricator of myconstruction embodying my improvements; Fig. 2, a central longitudinalsection, and Fig. 3 a horizontal section on the line y 3 of Fig. 1.Figs. 4 and 5 show thefriction-bearing brake for the bucket-shaft. Fig.6 shows different forms of dippers, and Fig. 7 shows the air-vent c ofthe reservoir-tube.

The case, which may be of approved pattern, is composed of two parts, Aand B, which are fitted together by a miter-joint, as shown, and areconnected at their upper ends by a hingejoint, a, in such manner thatthe part B can swing upward and rest upon the part A.

The shaft 0, journaled in bearings between the parts A and B, isextended out at one side of the case, and has the ratchet-wheelD keyedto said extended end. The bearings s for the shaft are divided into twohalves, and each half is carried by its respective parts A and B of thecase, and the parts are normallyseparated at the joint, so that theshaft is gripped by the halves of the bearings with sufficient frictionto' prevent the shaft 0 being carried too far forward when impelled bythe mechanism, presently to be described, or from retrograde movementwhen said mechanism is moving back to obtain a fresh purchase on theratchet wheel of the shaft previous to propelling it forward. This shaftis preferably screw-threaded, and is provided with a series of supportsor arms, E, at different points in its length, which carry dips orbuckets e, pivotally connected with their outer ends. These supports maybe disks, and the dips may be disposed around its periphery; but theyare preferably composed of radial arms forming spiders, which areadjustably held on the shaft between two sets of nuts, 0 6, one on eachside of each of the spiders.

The ends of the arms composing the spiders are bent to one side of theplane of the middle portion of the spiders to give clearance for thedips or buckets in the operation of the device and to prevent theirdischarging the oil upon the arms by coming in contact with the same. Byhaving the shaft screw-threadcd the spiders can be readily adjustedalong its length and to any desired angle, so as to evenly distributethe weight around the shaft.

The lower forward portion of the case is provided with a series ofoil-receiving chambers, G, which may be separate vessels placed thereinor a trough subdivided into a series of compartments by the partitionsg.

The short tubes 9 extend from each of these chambers, and are adapted tocarry the lubricant to the parts to be lubricated. The chambers are soarranged that the dips or buckets in their travel will rest against theinner sides of the walls of said chambers and deposit thelubricantthereon.

The reservoir H is provided at its bottom with the depending tube h,which opens into the reservoir and is closed by the valve I, having thestem or rod i, which projects below the end of the tube and is adaptedto strike the bottom of the case when the reservoir is placed thereinand lift the valve from its seat for allowing the lubricant to escapeinto said case or intermediate receiver till it closes the air-vent c inthe side of the tube, when the flow will cease until such air-vent isagain disclosed by the subsidence of the lubricant in the intermediatereceiver caused by the utilization of the same.

The mechanism for operating the lubricantfeeding devices consists,essentially, of the pawl J, the lever-K, and the cam L, or equivalentdevice, for vibrating the lever, which is mounted on the shaft 0 and hasits forward end It curved upwardly and rearwardly on the are of a circleof which the shaft is the center, and this curved end is is providedwith a series of openings, in any one of which the pawl J is pivot-allyconnected by the bolt l or other device.

The pawl is double-ended and reversible for throwing either end incontact with the ratchetwheel, according as (lesired. By having the pawladj nstably connected with the lever its length of stroke can beregulated for controlling the amount of feed of the lubricant.

The device can be thrown out of gear by means of the stop M, which canbe turned up u and will disengage the lever K from the cam L or otheractuating device.

In practice the device is placed at a higher level than the parts to belubricated, and the shaft is rotated by the devices hereinbeforedescribed, carrying the spiders or supports around in a circle. The dipsor buckets in their travel pass into the lubricant in the intermediatechamber, and, taking up a certain quantity, deposits it in the chambers,from which it is conveyed to the parts to be lubricated.

Referring to Fig. 1, it. will be understood that the cam-shaft may beoperated by any part of the mechanism to be lubricated, and connectedtherewith in any suitable manner.

I claim- 1. The combination, with the case having an intermediatereceiver and the oil-receiving chambers, and the devices composed of theshaft, the supports, and dips for carrying the oil from the intermediatereceiver to the oilreeeiving chambers, of the reservoir provided with anautomatically-operated valve and discharge-tube, which latter has anairvent which is closed by the lubricant in said intermediate chamberfor maintaining thelubri- 1 radial arms forming spiders, and having theends of the arms of each spider bent to one side of the plane ofthemiddle portion thereof,

l and having the dips or buckets pivotally connected with said ends ofthe arms upon the sides of the same bent farthest from the middles,substantially as described.

4. The combination, with the shaft screwthreaded about its entirelength, and the supports carrying the dips or buckets mounted thereon,of the nuts located on each sideof the supports for clamping them at anadjusted position to the shaft, substantially as set forth.

5. In an automatic lubricating device, the combination of aratchet-wheel secured upon the lubricant-feeding shaft, a rocking leverfuleru med upon the lubricant-feeding shaft and having one arm formedwith a segmental bar concentric with the fulcrum and provided with anumber of perforations, and an anchorshaped or double-ended pawladjustably pivoted by a pin or bolt in one of the said perforations andengaging the teeth of the ratchetwheel with either end, beingreversible, as and for the purpose shown and set forth.

6. In an automatic lubricating device, the combination of the lever K,operating the feeding device, an eccentriccam, L, engaging one end ofthe said lever, rocking the same when revolved, and a stop, M.adjustably secured upon a screw in a longitudinal slot of the stop, andhavinga bent end engaging and supporting the lever out of the reach ofthe cam, as and for the purpose shown and set forth.
